NOTE

Before installing a new IAC valve, measure the distance that the valve is extended. The measurement should be made from the motor housing to the end of the valve cone (pintle). The distance should be no greater than 1 ¹ / ₈ inch (28mm). If the pintle is extended too far, adjustment is required, otherwise damage may occur when the IAC valve is installed. Adjust the IAC valve by compressing the pintle to achieve the correct length.

4. Use a new O-ring, install the IAC valve and tighten the retaining screws to 18 inch lbs. (2 Nm).
5. Attach the electrical connector.
6. Connect the negative battery cable.
7. The PCM will reset the IAC valve the next time the ignition switch is turnedON and then OFF .
8. Start the engine and allow to warm to operating temperature to check idle quality.

This will help.
